The Safety and Efficacy of Autologous Transfusion in Spinal Surgery for Lung Cancer With Spinal Metastasis
A Single-center, Prospective, Randomized Controlled Study of the Safety and Efficacy of Autologous Transfusion in Spinal Surgery for Lung Cancer With Spinal Metastasis
Guangdong Provincial People's Hospital
118 participants
Mar 15, 2024
INTERVENTIONAL
Conditions
Summary
The goal of this single-center prospective randomized controlled trial is to test and compare the safety and effectiveness of autologous blood transfusion in spinal surgery for lung cancer spinal metastases. The main questions it aims to answer are: * Does autologous blood transfusion increase the incidence of new metastases? * Does autologous blood transfusion affect postoperative hemoglobin levels and the number of circulating tumor cells in the blood? * Can autologous blood transfusion reduce the rate of allogeneic transfusion during and after surgery for spinal metastases?

- Unable to obtain consent from the patient or family.
Interventions
Through a negative pressure suction device, the patient's blood that flows out during surgery is collected into a blood storage filter. During the suction process, it is mixed with an appropriate anticoagulant and passed through multiple layers of filters. When the volume of recovered blood reaches a certain level, it is continuously (or intermittently) centrifuged. Using a high-speed centrifugal blood recovery tank, the red blood cells are separated, and the plasma, waste, cell fragments, anticoagulants, and harmful components are diverted into a waste bag. A large amount of saline is used to repeatedly wash, purify, and concentrate the red blood cells. Finally, the concentrated red blood cells are prepared into a 70% red blood cell suspension with saline and stored in a collection bag for transfusion back to the patients. Open surgery is considered as the standard procedure for metastatic spinal cord compression
